Niba warigeze ukoresha itumanaho rya RF (radio frequency), imiyoboro ya selire, cyangwa sisitemu ya antenne, urashobora guhura nijambo LMR. Ariko mubyukuri niki kandi kuki ikoreshwa cyane? Muri iki kiganiro, tuzasesengura umugozi wa LMR icyo aricyo, ibiranga byingenzi, nimpamvu ariwo wahisemo kubisabwa na RF, hanyuma dusubize ikibazo 'Umugozi wa LMR ni iki?'.
Sobanukirwa na kabili ya LMR
Umugozi wa LMR numuyoboro wa coaxial wagenewe gukora cyane, gutakaza ibimenyetso bike byoherejwe mubisabwa na RF. Umugozi wa LMR wakozwe na Times Microwave Sisitemu kandi uzwiho gukingira neza, gutakaza ibimenyetso bike, no kuramba, bigatuma biba byiza kubitumanaho bidafite insinga GPS choice Guhitamo neza kuri radar hamwe nubundi buryo bushingiye kuri RF. Bitandukanye ninsinga gakondo ya coaxial, insinga za LMR zakozwe hamwe nuburyo bwinshi bwo gukingira hamwe nibikoresho bya dielectric kugirango tumenye neza ibimenyetso byerekana neza. Baza mubunini butandukanye kugirango bahitemo, nka LMR-195, LMR-240, LMR-400, na LMR-600, buri kimwe cyagenewe gutunganya amashanyarazi atandukanye hamwe nibisabwa gutakaza ibimenyetso.
Ibintu nyamukuru biranga umugozi wa LMR
Intsinga ya LMR igaragara mumurima winsinga za coaxial kubera imiterere yihariye nibyiza byo gukora:
1. Gutakaza ibimenyetso bike
Kimwe mu byiza byingenzi byinsinga za LMR hamwe no gutakaza ibimenyetso bike ni ukwitonda kwabo kure cyane (gutakaza ibimenyetso). Ibi bigerwaho binyuze murwego rwohejuru rwa dielectric insulation no gukingira, bigabanya gutakaza ingufu mugihe ibimenyetso byanyuze mumigozi.
2. Imikorere myiza yo gukingira
Igishushanyo mbonera cya LMR gifite ibice byinshi byo gukingira, mubisanzwe harimo aluminiyumu ikingira ikingira EMI y'ibanze (interineti ya electronique). Kuboha ingabo zo hanze byongera igihe kirekire kandi bikagabanya kwivanga. Uku gukingira gutanga ibimenyetso bikomeye kandi bisobanutse, bigatuma insinga za LMR ihitamo neza kubikorwa bya RF byoroshye.
3. Kuramba no guhangana nikirere
Times Microwave Sisitemu itanga insinga za LMR, icyuma cyacyo cyo hanze gikozwe muri polyethylene (PE) cyangwa elastomer ya termoplastique (TPE), bigatuma irwanya imirasire ya ultraviolet, ubushuhe, nubushyuhe bukabije. Impinduka zimwe, nka LMR-UF (Ultra Flex), zitanga ubundi buryo bworoshye bwibikorwa bisaba kunama no kugenda.
4. Kwubaka byoroshye kandi byoroshye
Ugereranije ninsinga gakondo zikomeye za coaxial, insinga za LMR zifite ubworoherane kandi bworoshye, bigatuma kwishyiriraho byoroshye. Iradiyo yabo igoramye ni ntoya cyane ugereranije ninsinga zisa na RF, zituma hashyirwaho cyane ahantu hafunzwe.
5. Guhuza na RF ihuza
Intsinga ya LMR ishyigikira abahuza benshi, harimo N-ubwoko bwa N (busanzwe bukoreshwa muri antenne na progaramu ya RF). Umuhuza wa SMA (kuri sisitemu ya simsiz na GPS). Umuhuza wa BNC (uzwi cyane mu gutangaza no guhuza imiyoboro). Uku guhuza gutuma bakora byinshi mubikorwa bitandukanye.
Porogaramu Zisanzwe za LMR
Kubera imikorere myiza, insinga za LMR zikoreshwa cyane mu nganda zishingiye ku itumanaho rya RF. Bimwe mubikunze gukoreshwa harimo imiyoboro idafite insinga na selire, sisitemu ya antenne na RF, GPS hamwe n’itumanaho rya satelite, porogaramu zo mu kirere, gukurikirana na sisitemu z'umutekano.
Hitamo umugozi mwiza wa LMR
Guhitamo ubwoko bwumugozi wa LMR biterwa nibintu byinshi, harimo inshuro, intera, gukoresha ingufu, nibidukikije. Hano hari amahitamo amwe:
LMR-195 na LMR-240: Bikwiranye na porogaramu ngufi nka antenne ya Wi Fi na sisitemu ya GPS.
LMR-400 loss Igihombo gito giciriritse gisanzwe gikoreshwa muri selile na sisitemu ebyiri.
LMR-600 suitable Birakwiriye cyane kubirebire birebire aho gutakaza ibimenyetso bigomba kugabanuka cyane.
Niba ukeneye guhinduka kwa porogaramu zigendanwa, umugozi wa LMR-UF (Ultra Flex) nawo ni amahitamo meza.
